The summer of 2006 had the highest minimum Arctic sea ice extent of the last decade.
Over the last two years, Arctic sea ice has closely tracked 2006.
This is due to the large increase in old/thick ice which has occurred since 2011. Older ice is much harder to melt in the summer, so there is less fluctuation between winter and summer.
The sea ice area anomaly graph has flatlined over the past 10 years.
Arctic sea ice is recovering, because the winds which had been pushing the old/thick ice out of the Arctic Basin are not as strong as they were during the previous 15 years.
Forecast polar vortex shows that Arctic air will return northeast US for about 10 days.

Thanks ren. It’s -14c (north of the border) Waiting for maple sugar season here. I have a question. Is the polar vortex dependent upon space weather?
Let us see solar cycle 16 and 24.

Find out what the temperatures were in 1934 and 2015. Very similar.

It is the height of about 45 km.

Stratospheric waves that occur in the winter arctic air pushing south.

Waves appear, with waves of decline in solar activity.
Stronger solar wind causes a decrease in temperature in the stratosphere in the winter and polar vortex acceleration.

So why does NASA say ice is declinig. A casual review of the NASA website shows Ice loss over the last several years. Are they adjusting the data or are they cherry picking?
They’re LYING! They have a hard time lying about extent because even this truck driver can access several great sites with a click of mouse to see charts and graphs and imagery. So “extent” is no longer the measure they choose to maintain their party line. Now their favored measurement is volume which is much easier to lie about by manipulation of data and cherry picking because we have not yet gotten to the point where satellites can measure the thickness of the ice apparently. It would be interesting to see what would happen when and if the thickness of sea and terrestrial ice can be measured over all by some kind of remote sensing in the way extent is.

Yikes!!
It seems like the “recovery” in Arctic sea ice has been cancelled. Oh dear.
Actually the “missing ice” is from areas outside the arctic. For example, because Siberia exported so much of its cold across the Pole to Canada this winter, there was less air flowing off the Pacific coast of Russia and forming sea-ice north of Japan. Much of the “missing ice” is from there, and from the area of the Pacific south of the Bering Sea.
Meanwhile in the Arctic Basin itself, the ice gets thicker and thicker, as the above graphics show.
The thing to do is quietly point this out, as Alarmists enjoy this brief “evidence” that the “Death Spiral” is back in business. Then sit back and wait. Once the yearly melt of over half the arctic sea-ice gets in towards the thicker ice, the sea-ice-extent graph is very likely to veer towards more average levels, especially as the AMO has dramatically swung into its “cold” phase..
I have a more long-winded description of what the ice has been going through this winter at a post here: https://sunriseswansong.wordpress.com/2015/03/09/arctic-sea-ice-maximum-why-so-low/
